A tear of a meniscus is a rupturing of one or more of the fibrocartilage strips in the knee called menisci.When doctors and patients refer to "torn cartilage" in the knee, they actually may be referring to an injury to a meniscus at the top of one of the tibiae.
Tears of the labrum have been credited to a variety of causes such as excessive force, hip dislocation, capsular hip hypermobility, hip dysplasia, and hip degeneration. [1] A tight iliopsoas tendon has also been attributed to labrum tears by causing compression or traction injuries that eventually lead to a labrum tear. [ 2 ]
The medial meniscus is a fibrocartilage semicircular band that spans the knee joint medially, located between the medial condyle of the femur and the medial condyle of the tibia. [1] It is also referred to as the internal semilunar fibrocartilage. The medial meniscus has more of a crescent shape while the lateral meniscus is more circular.
For the grading of osteoarthritis in the knee, the International Knee Documentation Committee (IKDC) system is regarded to have the most favorable combination of interobserver precision and correlation to knee arthroscopy findings. [10] It was formed by a group of knee surgeons from Europe and America who met in 1987 to develop a standard form ...
It is usually happening on one side, without a previous history of trauma. SONK should be considered together with differential diagnosis of osteoarthritis, tear of medial meniscus, and tibial plateau fracture. SONK usually has a sudden onset of knee pain, while osteoarthritis has a progressive, gradual onset of knee pain. [2]
Synovial osteochondromatosis (SOC) (synonyms include synovial chondromatosis, primary synovial chondromatosis, synovial chondrometaplasia) is a rare disease that creates a benign change or proliferation in the synovium or joint-lining tissue, which changes to form bone-forming cartilage.
Tunnel or notch view X-ray of the right knee from a patient with osteochondritis dissecans—cystic changes and irregular border are indicated by arrows on the medial side compared to the lateral side. Osteochondritis dissecans differs from "wear and tear" degenerative arthritis, which is primarily an articular surface problem. Instead, OCD is ...
